Hi Isuru,

See my comments below.=A0
=

- We may have room to improve the API of the xmlstreami= ng xpath and current api need to be cleaned up a bit.=A0
- We nee= d to add namespace support in xmlstream based xpath impl as it is commonly = used in most integration scenarios.=A0

-=A0xmlstreamingxpath is currently under synapse core util= s and its pretty much independent from synapse. We might move it some other= module than synapse-core.=A0
- Also during testing, I found = some limitations with text nodes(text()). We can work on improving those aspects as well= .=A0

- And I think we are good to go ahead with performance comparison for = CBR with xmlstream xpath and existing xpath support.=A0

Thanks.=A0
